.APPARATUS FOR MIXING AND PLACING MATERIAL FOR CONCRETE PAVEMENT.

SPECIFICATION forming part of Letters Patent NO. 672,934, dated April30, 1901.

Application filed December 22, 1899. Serial No. 741,247. (No model.)

To all whom it may concern.-

Be it known that I, CHESTER T. DRAKE, a citizen of the United States,residing in Chicago, county of Cook, and State of Illinois, haveinventeda new and usefulImprovement in Apparatus for Mixing and Placing Materialfor Concrete Pavement, of which the following is a specification,reference being had to the accompanying drawings.

My invention is an' apparatus for mixing and placing material forconcrete pavement.

The nature of myinvention consists in part in the apparatus provided tomix, carry, and place concrete material in a roadway to form concretepavement.

It consists also in part in the combination of such mixing and carryingapparatus, so that it may be moved simultaneously over the groundwithout causing any interruption to the operation of any of theapparatus.

In the drawings, Figure 1 is a side elevation, and Fig. 2 is a planview, of the carrier and a portion of the mixer.

B isaconcrete-mixer mounted upon wheels, so that it may be causedto,,travel over the ground.

Any suitable motor or engine (not shown) may be mounted upon the frameof the mixer to furnish the power for driving the mixing mechanism andalso to cause the groundwheels to travel over the ground when desired toshift the apparatus. 1

The materials, such as stone and sand, are supplied to the hopper of themixer in any suitable manner, and by the revolving of the mixing-shaftD, which is provided with knifearms H and shovel-arms I, the materialsare thoroughly mixed into concrete and discharged over the spout 5. Theshaft D, the knife-arms H and the shovel-armsl, and a suitable inclosinghopper are the principal elements of said mixing apparatus required forthe mixing of material for concrete pavement.

A strong upright frame 7 is provided at the discharge end of the mixer,and a guy rope or rod or a strong brace 8 is secured to the frame of themixer and to the top of the frame 7, and a guy-rope 8 is secured to thetop of the frame 7 and to the outer end of the carrier-frame C, so as tosupport the outer end of the carrier and allow it to swing to the rightor to the left as far-as may be required upon the vertically-disposedpivot-bolt 14, (dotted lines, Fig. 1.) The other end of the carrierframeis strongly secured to the discharge end of the mixer-frame by asuitable coupling which will permit such lateral motion of thecarrier-frame.

Suitable pulleys or rollers and a carrier-belt are provided in thecarrier-frame, and power from the mixer-motor is transmitted through thedriving-chain 10 to theshaft 12, which is secured to the under sideof-the carrier-frame. The chain 10 passes between two loose rollers 11,which are secured to the under side of the mixer-frame, so as to retainthe driving-chain at or near the vertical pivotal center of the lateralmotion of the carrier-frame, and a driving-chain from shaft 12 transmitsthe power to the carrier-driving shaft 13 and to the carrier-belt 6, soas as to cause it to revolve continuously and carry the mixed concrete,which falls from the spout 5 onto the belt, away from the mixer anddeposit the concrete in any part of the pavement as the carrier is swungto the right or to the left, and then the concrete may be tamped in theusual manner.

Power may be applied to cause the groundwheels to travel over the groundwithout any interruption of the operation of the mixer or of the carrierC, and the whole apparatus may be moved to any place to facilitate thework.

I claim as my invention 1'. In combination with a mounted mixer, of acarrier in close proximity to the mixer supported from the frame of themixer in a manner to permit a lateral swinging movement thereof adaptedto receive and convey the material discharged from the mixer, and meansfor operating the carrier comprising a driven chain geared to the rearend of the carrier, and guides through which said chain is adapted totravel, as and for the purpose described.

2. In combination with a mounted mixer,

of a carrier in close proximity to the mixer supported from the frame ofthe mixer in a manner to permit a lateral swinging movement thereofadapted to receive and convey the material discharged from the mixer,and means for operating the carrier comprising a power-driven chain, andintermediate gearing instrumentalities between said chain and the rearend of the carrier, substantially as described.
